In addition, a pre-column derivatization HPLC method was applied to the determination of Astragaloside Ⅳ; the flavonoids was determined by full-range HPLC scanning; a colorimetric method was developed for the determination of flavonoids and saponins. Hierarchical cluster analysis was performed on three constituents of different Radix Astragali species, and its result was compared with those of traditional phytoecological identification and the pharmacological quality assessment.

本研究以比色法测定了黄芪中总皂苷的含量，以柱前衍生化高效液相色谱法测定了黄芪中黄芪甲苷的含量；以比色法测定了黄芪中总黄酮成分的含量，以反相高效液相色谱法测定了黄芪中毛蕊异黄酮和毛蕊异黄酮苷的含量；以黄芪中的黄芪甲苷、毛蕊异黄酮和毛蕊异黄酮苷为主要特征对不同品种的黄芪进行了系统聚类分析，并将聚类结果与传统生药学鉴定和药理质量评价结果进行了比较。

Fromthe point of view of chemical components,α-cellulose content for differentage-degrees bamboo is mostly the same,slightly increasing with the growth ofage,lignin content increases with the growth of age,the contents of extract,hemicellulose,polysaccharose,mineral elememts decrease with the growth ofage;the result shows the electric conductivity of bamboo is mainly decided bythe content of mineral elements,with the growth of age,volume resistivitybecomes great.pH value shows acid,acidity decreases with the growth of age,this is mainly due to the decrease of fraction of bamboo parenchyma with thegrowth of age.

从化学成分角度来说，不同年龄竹材α-纤维素含量差异不大，一般随着年龄增大而增大；木质素含量随着年龄增大而增大；抽提物、半纤维素、聚戊糖、灰分含量随着年龄增大而降低；研究表明竹材的导电性主要由矿质元素含量大小决定，随着年龄增大，体积电阻率越来越大；pH值呈酸性，酸性随着年龄增大而减弱，这主要由于竹材薄壁组织比量随着年龄增加而减少，内含物如淀粉减少，导致酸性减弱。
